Part number for replacement bulb on model vs50501 and ballast part number

Replace bulb and or ballast.

Use an 8 inch Circline T9 daylight LED and directly relamp fluorescent FC8T9 bulb without rewiring

ballast--- -usually a ballast transformer used in flouresent lights to turn 120 volts ac into 2000 or 3000 volts ac at a lower amperage. the ballast transformer has 4 nuts ,one at each corner for physical mounting .2 wires for the ac line cord and 4 wires for the flouresent tube. wires are connected together with wire nuts that can be pulled off the wires while unscrewing the wire nuts.
make a picture of what color wires go where,take wires off one at a time and make pictures. the wires are not interchangable and must go back exactly where they came off from or the unit will never work again.
many ballast transformers have an electrical diagram showing where the wires go. you may need a magnifing glass to see it well enough read it. Please study the diagram and understand it before you begin disassembly.
WARNING: You must make sure that the electriic cord is unplugged or the circuit breaker on the OFF POSITION
with the electricity on ,you can be electrocuted by either the 120 volts ac or the 3000 volts ac that means crash,burn and fry.
so de-energize first.
The replacement ballest must be rated for the wattage of the flouresent bulbs ,the length of the flouresent bulbs and the diameter of the flouresent bulbs. that are in the lighting fixture. the flouresent bulbs also have their own make and model numbers.the model numbers of the bulbs are standardized throughout the industry. The model number of the flouresnt bulbs that a ballast will work with is on thw ballest sticker, on the cardboard box and on the directions.the salesman in the flouresent ballest [lamp] section at home depot or lowes should also be able to help you.

The ballast is a power supply for the lamp---it produces over 10,000 volts to fire and run the lamp----when you replace the lamp the two wire plug it connects to goes direct to the Ballast.

The spark plug type wires are there for a good reason--lots of rf there.

Double check lamp went in correctly and mated with the plug it goes into.

Looking to try a ballast: Google the model number with the word ballast.

There is a ballast which drives the lamp--a hint would be to try to be in a position if possible to see if lamp ignites at all or even for a moment.

The ballasts do fail but rarely----it develops about 12,000 plus to the lamp and is much like spark plug wires as far as rf.

Some checks would have to be made and then the ballast priced--google the model number with ballast after it to get and idea.

No cut and dried solution here--several possible causes.

1. • 1 Open the hood and reach down into the engine bay for the fog light assembly. If you cannot reach the fog light assembly from the top you may need to get underneath the truck to reach it. Remove the electrical plug running to the fog light ballast.
     
   • 2 Remove the bulb. Unlock the fog light bulb by turning it counterclockwise and pulling it straight out of the assembly.
     
   • 3 Slide a new bulb into the fog light assembly. The part number you will need for the new bulb will be located on the ballast or base of the old bulb.
     
   • 4 Turn the bulb clockwise to lock it into the fog light housing.
     
   • 5 Reconnect the electrical connector to the bulb ballast.
     

The ballast for the lamp too should be replaced along with the lamp. If you wish to get some details; visit the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/

go on the samsung website get the part number and then go on ebay and purchase the ballast. its half the price. pull out lamp assembly and right under it is the ballast. 2 or three screws hold it in. and there are 2 plugs that need to be undone. its very easy. hope this helps. i did it in about 15 min
